What it is

The Baxi 402S186 is a limit thermostat supplied by Baxi. It is a safety device that interrupts the appliance's heat demand when the sensed temperature rises above the set limit, helping to protect the heat exchanger and surrounding components from overheating. It is listed as the Baxi 402S186 Limit Thermostat and is ordered against that part number.

Before you order

  • Confirm the part number on the existing thermostat matches 402S186.
  • Check the appliance's data badge and manual to confirm the correct limit thermostat for the model.
  • Inspect the mounting and capillary or lead arrangement on the existing part before ordering, as these vary between thermostat types.
